Modelling Resource Values and Climate Change Impacts to Set Preservation and Research Priorities

ABSTRACT

Climate change impacts will increase in their frequency and severity in the coming decades, resulting in compromised integrity or destruction of thousands of heritage resources. Efforts are needed to identify, record, and study resources that will be affected. To set research and preservation priorities, the vulnerability of resources to climate change impacts and their importance to scientific research, preservation, and other resource values needs to be understood. We advocate a modelling approach which predicts the location, timing, and severity of climate change impacts; identifies resources at risk, their resource values, and opportunity costs; and prioritises research and preservation options based on these assessments. The need for this approach is illustrated with examples from two coastal areas subject to different impacts and hosting different types of heritage resources: the Atlantic coast of Georgia in the United States and the Wismar Bight along the Baltic Sea in northern Germany.     

Editorial: The Nordic World Heritage Foundation

Abstract

This article identifies the current state of knowledge in the literature regarding the possible impacts of future climatic change on archaeological sites and ensembles. Drawing on the literature review a matrix of potential impacts is collated to provide a simplified overview. This theoretical ‘menu’ is then tested by applying it to a vulnerability assessment of the World Heritage site of Skellig Michael in Ireland. The case study results reveal some knowledge gaps, particularly in regard to the impacts of climate change on buried archaeological remains.     

Burning Libraries: A Community Response

ABSTRACT

The first decade of the twenty-first century has seen a growing recognition that widespread impacts of climate change (erosion, sea level rise, wildfires, warming soil temperatures) are rapidly destroying archaeological sites and permanently wiping out millennia of cultural heritage and important scientific data on a global scale. This paper provides a brief overview of the efforts of the international archaeological community and its allies to organise a broad and coordinated response to this widespread and urgent threat to our basic record by mobilising at the local, national and international level. The work of the archaeological professional societies has supplemented a growing host of initiatives on multiple scales by national and local governmental agencies, regional research teams, local and Indigenous heritage groups and the international global change scientific community. This paper provides some reflections on the Society for American Archaeology’s Climate Change Strategies and the Archaeological Record team effort from 2015 to 2018, some links to more contacts and resources and some suggestions for future directions.     

Weather sensitivity and climate change perceptions of tourists: a segmentation analysis

ABSTRACT

Many communities rely on tourism spending, so it is important to understand any potential changes to tourist flows resulting from changing climate and weather patterns. However, tourists are not a homogenous group, as they have different motivations, values, and goals. Therefore, the purpose of this investigation is to better understand potentially varying perceptions and behavior of different tourist types, specifically in regards to their weather sensitivity, climate change concern, and behavioral intention for climate change mitigation. Tourists were randomly surveyed at 20 locations throughout the state of Maine in the United States (n = 704). Segmentation analysis on the activities tourists participated in yielded three segments of Maine tourists: non-nature-based tourists (50.6%), nature-based generalists (16.2%), and nature-based specialists (33.2%). Differences across segments were explored for perceptions of weather impacts, climate change concern, and mitigation intent. Additionally, weather sensitivity was analyzed based on type of overnight accommodations to better understand if this also had a role in differences. Non-nature-based tourists thought that weather variables were less influential during their travels in Maine than the other segments, while nature-based generalists perceived weather to have the highest influence. Additionally, nature-based specialists had the highest level of climate change belief, while nature-based generalists had the highest willingness to engage in climate change mitigation behavior. Results are useful to understand how segments of tourism demand may be altered with a changing climate, such as increased temperatures, precipitation, and storms, and what groups may be the most beneficial to target for marketing or educational efforts to reduce the impact of climate change.     

The archaeology of climate change in the Caribbean

This paper emerges from an attempt to more actively integrate archaeology with ongoing geographical and environmental discussions of human responses to the effects of climate change in the Caribbean. If archaeology is to contribute to the mitigation strategies currently being developed, then robust interpretations are necessary that can be practically integrated with inter-disciplinary action. This paper discusses the methods needed to provide the high-resolution data and interpretations required using archaeological and palaeoenvironmental research from a case study area in northern Cuba. Using data collected from an ongoing collaborative archaeological research project with the Cuban Ministry of Science, Technology and Environment, we evaluate whether it is possible to make useful interpretations of human response to past changes in sea-level, precipitation and hurricane activity. Specifically, the effects of these activities on the changing nature of settlement locations, food procurement strategies and household architecture among pre-Columbian communities are evaluated. Indigenous mitigation strategies are identified and used to inform modern day preparation for the impacts of climate change in the Caribbean.     

Managing,Valuing, and Protecting Heritage Resources in the Twenty-First Century: Peatland Archaeology,the Ecosystem Services Framework,and the Kyoto Protocol

Abstract

This paper argues that the development of the Ecosystem Services framework, which has recently emerged as an internationally recognized framework for valuing ‘the ‘natural capital’ of ecosystems, presents a number of opportunities for heritage management and the archaeological record, arguing that the inclusion of archaeological and palaeoenvironmental ‘value’ within this framework presents an opportunity to incorporate heritage alongside a range of other critical ‘services’. It presents a short case study focusing on the problems facing the preservation of peatland archaeological sites and deposits in situ alongside developments within peatland conservation and restoration initiatives partly driven by the ability of healthy, functioning peatlands to sequester carbon and hence mitigate climate change. It is argued that this drive towards peatland re-wetting may bring both positive benefits and opportunities for heritage management but also presents a number of practical issues, which now require active engagement from the archaeological community.     

Costs and benefits of environmental change: tourism industry's responses in Arctic Finland

ABSTRACT

Recent research has focused on the impacts of environmental change to tourism. In particular, the perceived costs of climate change have been increasingly studied. However, the relationship between costs and benefits resulting from the changing environmental conditions for the industry has been less examined. This paper identifies the locally observed changes in the natural and socio-economic environments and aims to analyse the financial costs and benefits to tourism businesses in two tourism-dependent communities in northern Finland. The specific focus is on adaptation and adaptive management in a tourist destination scale. Adaption is understood as an investment creating not only implementation costs, but potentially also benefits for tourism operations. Research materials were collected among tourism and tourism-related businesses through 41 semi-structured thematic interviews. Results indicate that the evaluated benefits of environmental change seem to exceed those of costs. This conforms to the on-going discourse of climate change–tourism relations associated with the Arctic region where both awareness and vulnerability to change are considered relatively high but the level of responses, i.e. adaptation, low. These results can help to further identify the most vulnerable sectors in tourism and assist entrepreneurs preparing for environmental and climate change. However, the paper concludes that while global environmental change, with specific adaptive management strategies, may create local short-term direct benefits for the industry, a long-term sustainability of tourism in the Arctic calls for mitigation responses to climate change.     

SIFTING THE SANDS OF TIME: GEOARCHAEOLOGY,CULTURE CHRONOLOGY,AND CLIMATE CHANGE AT SQUIRES RIDGE,NORTHEASTERN NORTH CAROLINA

Abstract

Since 2000, East Carolina University has conducted archaeological research in the Tar River valley in the northern Coastal Plain of North Carolina designed to address poorly understood aspects of the region’s culture-history. In particular, survey and excavation along a portion of the Tar River have focused on problems related to Coastal Plain chronology, typology, and geoarchaeology. Here we provide an overview of testing done at one site, Squires Ridge, that contains stratified Woodland and Archaic period remains in a 1-m deposit of largely aeolian sandy soils. We suggest that the formation of the archaeologically stratified portions of sand ridges along the Tar River reflect millennial-scale climatic cyclicity representing regional manifestations of climate change during the Early to Middle Holocene. Sand ridges along the Tar River likely represent proxies of climate change, while the archaeology contained within them manifest human adaptations to such change.     

Climate change and security: examining China's challenges in a warming world

The environment is increasingly affected by global climate change. While the causes of climate change are generated across the globe, the impacts of climate change will be highly variable at the local level. An increased scientific understanding of the potential impacts that climate change may have within China has raised new concern among China's leaders. Given that China's domestic realities inform its international policy choices, understanding how climate change may affect its population and natural resources is critical to global climate stabilization efforts. This article examines how the impacts of climate change on China, and China's response, will drive security challenges domestically, as well as in the greater Asian region and around the world. It shows that the impact of climate change on China will be significant and may have sizable adverse economic implications, particularly on vulnerable east coast economic centers. Water scarcity is a problem that already challenges China's leadership and one that will be exacerbated under projected climate impacts. In addition, the country faces the risk of international retaliation should it fail to undertake serious greenhouse gas mitigation actions. Yet China is not without options, and is already well poised to become a leader in the low-carbon technology revolution.     

The Middle Stone Age of West Turkana,Kenya

Abstract

Research on the origins of Homo sapiens and the development of our species’ unique behavior is focused on the Middle Stone Age (MSA) period in Africa (in comparison with the European Upper Palaeolithic). Although archaeological and paleontological fieldwork in the Turkana Basin in northwestern Kenya has contributed greatly to our understanding of human evolution in Africa, the Basin's MSA archaeological record remains poorly known. We report on a reconnaissance of MSA sites in West Turkana, Kenya, which included known archaeological/paleoanthropological localities at Eliye Springs and Kabua Waterhole (Kadokorinyang). A newly-discovered site, Nakechichok 1 (GdJh 5), preserves MSA tools stratified beneath Late Stone Age assemblages. The MSA lithic artifacts from Nakechichok 1 differ from those known from other MSA localities in nearby regions, and, they expand the known scope of MSA variability in the Turkana Basin, demonstrating that the MSA is not “missing” in this region, but just hard to find.     

Mineral weathering in forest soils and its relevance to the preservation of the buried archaeological resource

There is more woodland in Britain now than for many centuries and considering many international climate change mitigation policies, woodland cover, both in Britain and internationally, is being promoted. However, neither the management of existing woodlands nor their expansion should be at the expense of important archaeological evidence. Due to the large number of known archaeological sites, the large areas of land with uninvestigated archaeological potential and the expanding woodland cover, suitable mitigation strategies need to be developed to allow preservation in situ of important sites. An understanding of how woodland soils and the buried archaeological resource interact is, therefore, essential. This paper utilises ongoing environmental research into the mineral weathering rates in forest soils and considers its application to artefact preservation. The study concludes that soil water pH, its movement, and the saturation of dissolved ions in the soil solution are major factors determining both mineral and artefact longevity. A simple guide to artefact longevity based on these properties is proposed and a geochemical model for predicting loss is tested. These tools could be applied to any soil or individual horizon irrespective of land-use.     

Dealing with Tribes and States in Ancient Palestine

This paper offers a critique on state formation theories used in the explanation of the rise of the biblical United Monarchy. The last three decades of archaeological and biblical research have shown that there is no firm evidence for speaking of a kingdom or empire of David and Solomon in ancient Palestine. Thus what is proposed here is to evaluate the archaeological record through the data provided by the ethnological record of the Middle East, keeping the biblical stories apart from this interpretation. The analysis of the dynamics and structure of Middle Eastern “tribal states” and “chiefdom societies”, including here the practice of patronage bonds, gives us important keys for understanding Palestine's societies. The historical perspective that appears then is one different from the Bible's stories and from modern ideas such as “states” and “nations”, offering us instead a better methodology for reconstructing ancient Palestine's historical past.     

From conflict archaeology to archaeologies of conflict: remote survey in Kandahar,Afghanistan

ABSTRACT

Emerging from research with the Afghan Heritage Mapping Partnership, a multi-year project using satellite imagery to detect, record and manage archaeological heritage, this paper examines the potentials of remote-sensing to not only monitor archaeological material culture, but also contemporary materiality as it is violently (re)assembled through conflict. Through systematic remote-sensed archaeological survey using diachronic imagery in Kandahar, Afghanistan, this work expands archaeological understanding of an under-surveyed region while exploring the impact of the region’s expansive military infrastructural footprint on cultural heritage. Further, this research considers the long history of landscapes of control and successive military occupations. Remote survey allows for continued generation of archaeological data during conflict, thereby enabling more thorough heritage management. Finally, this survey demonstrates that, although remote aerial technologies have been criticized as tools of violence, surveillance and control, satellite imagery can be used analytically to generate new understandings of and challenges to military infrastructural reach.     

The Rose Theatre: Twenty Years of Continuous Monitoring,Lessons, and Legacy

Abstract

The discovery of the Rose Theatre in 1989 led to the implementation of new planning guidance focused on the presumption that the preferred response to development impacting on archaeological sites would be mitigation and preservation in situ. There was little understanding of what the impact of mitigation would be on the quality of the buried evidence and the Rose Theatre site was the first to be scientifically monitored. As a direct result research was implemented and the PARIS series of conferences were initiated.     

Radiocarbon chronology and the correlation of hunter–gatherer sociocultural change with abrupt palaeoclimate change: the Middle Mesolithic in the Rhine–Meuse–Scheldt area of northwest Europe

Recent refinements in radiocarbon sampling procedures have enabled a more robust absolute chronology for the Mesolithic in the Rhine–Meuse–Scheldt area of northwest Europe. These refinements have allowed for a new chronological sub-division of the Early and Middle Mesolithic periods. Results of this research have indicated that the Middle Mesolithic period was bound by two Early Holocene cooling events, one at 9300 cal. BP and the other at 8200 cal. BP. These results enable a critical evaluation of the role of chronological precision in the investigation of contemporaneity between abrupt climate change and hunter–gatherer sociocultural change. In this paper we focus on the variable chronological resolution of the Early to Middle and Middle to Late Mesolithic transitions in the RMS area, and the role of this variable resolution in our ability to investigate the contemporaneity of these two transitions with different Early Holocene abrupt cooling events. This paper highlights two central challenges facing archaeological investigations of the relationships between climate and culture change: first, the requirement of tight chronological overlap between climate and culture change events and consideration of leads and lags in ecosystem and subsequent human responses to climate change; second, the equifinality problem and the separation of the impact of gradual from punctuated environmental change on human societies.     

Presenting the San Hunter-Gatherer Past to the Public: A View from the uKhahlamba-Drakensberg Park,South Africa

Abstract

The uKhahlamba-Drakensberg Park (UDP) was declared a World Heritage Site in 2000 on the basis of its magnificent scenery, biodiversity, and archaeological richness, comprising a rich corpus of rock paintings and occupation deposits relating to the San hunter-gatherers. The desire to encourage heritage tourism to the UDP following the declaration, along with the wish to present a more positive picture of the San hunter-gatherers, led to the development of the Kamberg (in 2002) and Didima Rock Art Centres (in 2003). These centres, together with the Main Caves visitor attraction, which had been redeveloped in 1998, distinguish the UDP as the premier region in South Africa for the interpretation of the San past. Cognizant of the critical role that public interpretation plays in the management of archaeological resources, this paper investigates which aspects of the archaeological record have been stressed and which have been overlooked, the relationship between the interpretations and the findings of UDP archaeological research since the 1970s, and whether these findings enhance the significance and value of the resources and thereby promote their management. It is shown that the overall interpretive emphasis is on rock art and that information derived from Later Stone Age hunter-gatherer excavations since the 1970s have been neglected. Furthermore, it is revealed that the display of Early and Middle Stone Age material at Didima is inconsistent with regional archaeological findings and that there is a neglect of local archaeological remains. It is concluded that the development of any further attractions should be based on an interpretive plan which considers the interpretive requirements of the region as a whole.     

Migration and Cultural Change: The Northern Iroquoian Case in South-Central Ontario

This paper explores processes of cultural change by contrasting migration scenarios with in situ cultural development. I argue that a detailed, fine-grained analysis of patterning within the archaeological record provides the means with which to distinguish between these scenarios. The archaeology of the Rice Lake–Trent River region in south-central Ontario provides a case study for the investigation of these processes of cultural change across the Middle to Late Woodland transition and in relation to the origins of Northern Iroquoians. Expectations for ceramic patterning are derived from each cultural change scenario and then evaluated against the regional database. This assessment is facilitated through the use of two statistical techniques: frequency distributions and correspondence analysis. The results clearly demonstrate both continuity and patterned change within the region, thus supporting the in situ hypothesis. I place these findings in a broader context through comparisons with contemporary developments in southern Ontario, southwestern Quebec and northern New York State.     

Hesitant hunters: a review of the introduction of agriculture in western Norway

Abstract

Evidence for the introduction of agriculture in western Norway is presented, using three categories of data: (1) palaeobotanical data, including pollen diagrams from lakes, bogs and archaeological sites, focusing on the presence of cereals, Plantago lanceolata L. and anthropogenic pollen indicators, and charred macro remains of cereals from archaeological sites; (2) osteological data, focusing on the occurrences of bones of cattle, sheep and goats in three rock-shelters, and the bone material from one open-air Neolithic site; (3) archaeological data, including artefacts indicating agricultural practices, distribution of residential settlement sites, and stray finds. The evidence for agricultural activity at the beginning of the fourth millennium BC (Early Neolithic, EN) is low, whereas the presence of both cereals and animal husbandry is indicated in the palaeobotanical material from the Middle Neolithic A (MNA, 3400–2600 cal. BC). The earliest record of domesticated animal bones is dated to the Middle Neolithic B (MNB, 2600–2200 cal. BC), while palynological and archaeological data also indicate an expansion in the area cultivated by early farmers. All data confirm the establishment of an agrarian society and animal husbandry in the Late Neolithic (LN, 2200–1700 cal. BC). It is concluded that agriculture was introduced into western Norway by the indigenous hunter-fisher populations. During this process, social and ideological factors played principal roles.     

Archaeological wells in southern France: Late Neolithic to Roman plant remains from Mas de Vignoles IX (Gard) and their implications for the study of settlement,economy and environment

Abstract

A study of plant remains from seven archaeological wells at Mas de Vignoles IX, near Nîmes, southern France, was used to shed light on a current gap in the archaeological record caused by erosion and modern agriculture. The analysis also explored the reliability of these sources for palaeoenvironmental and palaeoeconomical information. Significant results on the spatial organization of human habitation, economic activities, and on the environment and its exploitation were obtained for the Middle Neolithic to Roman periods. Furthermore, the Neolithic wells also provided the first early finds of fig seeds in France. The abundance of weed and ruderal plants up to the Iron Age is consistent with data from other studies and their dramatic decrease during the Roman period may have resulted from radical changes in land management. The study marks the first time, in southern France, that a group of wells from a single site have provided a complete record throughout the later prehistoric and Roman periods.     

Archaeology and Development: the Tembladera Sites of the Peruvian North Coast

Abstract

Utilizing the example provided by a major water-control project planned for construction in the Jequetepeque Valley on the Peruvian north coast, this paper emphasizes a number of problems in the implementation of cultural resource-management programs in the Third World. The impact of this particular economic development program on the archaeological record is demonstrated by focusing on the project's most devastating aspect, the construction of a large dam in the up valley region just south of the town of Tembladera. Special attention is given to the threatened Chavin-related sites in this region, sites about which little is known other than that they are characterized by a highly valued ceramic style often found in private and museum collections.
